3A, 23V, 385KHz Step-Down Converter
FP6189
General Description
The FP6189 is a buck regulator with a built-in internal power MOSFET. It can provide 3A
continuous output current over a wide input supply range with excellent load and line regulation.
Current mode operation provides fast transient response and eases loop stabilization. The device
includes cycle-by-cycle current limiting and thermal shutdown protection. Adjustable soft-start reduces
the stress on the input source during power-on. The regulator only consumes 20μA supply current in
shutdown mode. The FP6189 requires a minimum number of readily available external components to
complete a 3A buck regulator solution.
